(a)
Interpretation:
The relative priorities for the given set of substituents have to be assigned.
Concept introduction:
E-Z designators are used as like cis-trans terminology for non-similar groups attached
In E-Z designations, the groups attached to vinylic positions are checked by their priority on the basis of higher atomic weight of connected atom, if it is same for the connected atom then consider the next atom of each group and so on. In case of multiple bonds connected with same atoms, then the higher bonds having group has higher priority.
(b)
Interpretation:
The relative priorities for the given set of substituents have to be assigned.
Concept introduction:
E-Z designators are used as like cis-trans terminology for non-similar groups attached alkenes.
In E-Z designations, the groups attached to vinylic positions are checked by their priority on the basis of higher atomic weight of connected atom, if it is same for the connected atom then consider the next atom of each group and so on. In case of multiple bonds connected with same atoms, then the higher bonds having group has higher priority.

- What reagent is necessary to complete the reaction? CH3-CH2-CH-C-OH ? CHỊCH,CH C-0- Na* CH3 CH3 NaO O NaCl O Na O NaOH + H₂Oarrow_forwardOChem help with IUPAC names involving Ph and Bn The phenyl group (Ph-R, C6H5-R) can be formed by removing a hydrogen from benzene and attaching a substituent to where the hydrogen was removed. The benzyl group (abbv. Bn), similar to the phenyl group, is formed by manipulating the benzene ring. In the case of the benzyl group, it is formed by taking the phenyl group and adding a CH2 group to where the hydrogen was removed. Its molecular fragment can be written as C6H5CH2-R, PhCH2-R, or Bn-R. Please provide the IUPAC name for the following: (Ph)2CHC(CH3)2CC(CH2)3CH(Bn)CHOarrow_forwardAnswer the following questions regarding a reaction shown below. For IUPAC naming, indicate absolute configurations using R/S sequence rule. For Fisher projections, all the carbons must be vertically lined up from C1 (top) to C4 (bottom). Give an IUPAC name for the starting material. Q1: Draw one of the two products of chlorination at C3 in Fisher projection. Q2: Provide the IUPAC name of Q1. Q3: Draw the other product of chlorination at C3 in Fisher projection. Q4: Provide the IUPAC name of Q3.arrow_forward
